Hi Greg,

I have the Summilux version, the 35 1.4 Asph.  It also has a loose-ish
aperture ring, compared to some other Leica M lenses.  They're all a bit
different actually.  I've also noticed some variation from one lens to
another of the same model.  Call it 'personality'.

Knowing that other Leica lenses have loose aperture rings, like some of
mine, might help you sleep at night, but if it doesn't, try hitting the
bottle real hard, or get that lens back to a dealer or agent and ask for a
second opinion.

How are the pictures?  Oh! Probably honeymoon shots, oops, sorry for asking
